Acquiring information about a natural feature or phenomenon, such as the Earth's surface, without actually being in contact with it. USGS remote sensing is usually carried out with airborne or spaceborne sensors or cameras.

Site for the Optical Science Laboratory specializing in expert calibration of aerial mapping cameras with links to fees, scheduling cameras for calibration, historical camera database files, USGS aerial camera specifications, and how to visit.

Site to learn about, view, and order digital image vegetation condition (greenness) maps of the conterminous U.S. based on the Normalized Difference Vegetation Index (NDVI) with imagery from Advanced High Resolution Radiometer (AVHRR).

Site for the Platte River Program in Nebraska an area that is a critical staging area for migratory waterbirds of the Central Flyway. Includes links to color-infrared aerial photos, 1938 historic aerial photos, and Cottonwood Ranch research site.

Shows how we can use remote sensing to study natural phenomena that vary seasonally but whose timing is affected by both shorter- and longer-term variations in climate or other, similar environmental conditions.

Report on satellite imagery collected by the NOAA Advanced Very High Resolution Radiometer (AVHRR) on NOAA polar-orbiting weather satellites. Links are provided to imagery of north-central Gulf of Mexico and of the Lake Pontchartrain.

Explanation of uplift in the land surface of the northern part of the Yellowstone caldera (12cm, about ~5 inches) that occurred between 1997 and 2003, including the scientific methods by which it was detected and analyzed.

Ordering and descriptive information for National Aeronautics and Space Administration (NASA) imagery acquired by the USGS from Gemini, Apollo, Skylab, International Space Station, Space Shuttle, and Shuttle Large Format Camera missions.

This publication (Open-File Report 95-479) is a teacher's guide to two U.S. Geological Survey maps that show gravity and magnetic data in contour form superimposed on a LANDSAT satellite image of the San Francisco Bay area.

With NASA and JPL, USGS provides satellite images that anyone can use to see changes in the Earth's surface over time. This helps us study changes due to climate, human activities, or meteorological events.

The primary goal of U.S. Geological Survey (USGS) Natural Hazards Response is to ensure that the disaster response community has access to timely, accurate, and relevant geospatial products, imagery, and services during and after an emergency event.

We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
